For my money, the most surprising high-value secure website feature is search (here we mean natural language keyword search that lets a user find what he or she is looking for on the site). In fact, our research revealed search to be one of the few bank website features that customers rate as above-average in importance, yet search is either nonexistent or poor on most banks’ secure sites. So we wrote an entire research report about it. Here are some highlights:

Online banking customers want search… We asked consumers who bank online to "rate how important it is to you that your bank's website has each of the following features" and asked them about 14 different features, including search. The majority of online bankers — 68% in the US and 63% in Canada — say search is important to have on their bank's secure website.

…but few banks offer search on their secure website…Just seven of the 25 largest banks in North America include search functionality on their secure websites.
